I have no issue updating my MT-Card. Did you follow the exact steps per the instructions on updating to 1.2? It's a little different than previous version like updating the driver and waiting a while for the driver to update before it continues.

Mine died on 1.2 update, I emailed them and they told me to do a manual driver update, there isn't any drivers..
I emailed them again and haven't had anything back since.
I'm going to wait for the new Evo card, they showed us stuff working before even Gateway did, I don't trust Gateway's software for bricks and MT aren't able to fix their own hardware.
I think it's time for a change.
